GUIDE FOR TROLLEYSFOR TROLLEY-WHEELS 0F OVERHEAD TROLLEYS FOR ELECTRIC CARS Hamilton'and State of Ohio, have invented certain new and useful Improvements in Guides for Trolleys for Trolley-Wheels of Overhead Trolleys for Electric Cars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part ofthis specification.

The purpose of my invention is to provide an attachment for the trolley poles used in making connection with the overhead trolley which will enable the operator to readily find the trolley wire and to guide the trolley wheel thereto whenever for any reason the wheels have to be shifted from one line to another or the trolley wheel has become accidentally displaced from the wire.

My object is to furnish a construction which consists of a minimum number of parts, which can be readily and easily attached to the trolley pole and which shall be so constructed as not to interfere in any way with the ordinary use of the trolley pole, and in the event of accidental dislodgment of the pole will tend to ward off the overhead structure and prevent the breaking or tearing of the wire supports.

The invention consists of that certain novel construction and arrangement of parts to be hereinafter particularly pointed out and claimed whereby the above results are attained.

In the drawings, Figure 1 is a side elevation of my invention showing the trolley wheel on the wire. Fig. 2 is atop plan view of the same. Fig. 3 is a side elevation with the trolley guide in use. Fig. 4 is a detail perspective showing the attachment of the pulling rope to the guide. Fig. 5 is a front view of the clamp for securing the guide to the trolley pole.

The trolley guide comprises a bar 1, with projecting forks 2, 2, at one end, and at the other end 3 a means for securing the pulling rope 4: to the guide. The guide bar 1 is pivotally mounted by the bolt 5 to the plate 6 shaped on its opposite end 7 to engage the trolley pole 8, and forming with the corresponding plate 9 similarly shaped at 10 a pair of clamp plates for securely clamping Patented Dec. 21, 1915.

the clamp members so that in the event of the trolley wheel 13, which normally rides underneath the trolley wire 14 being accidentally dislodged, no obstruction will be formed to catch or injure the wire supports.

For attaching the trolley rope to the guide bar, I have found that a very perfect means for quickly attaching the pulling rope is to provide two holes in the end of the guide bar and push the end of the pulling rope up through one of these holes and down through the other, as shown in Fig. l.

The forks 2, 2, of the guide are curved rearwardly and flare outwardly as shown in the drawings, and the shank portion immediately below the forks is curved as shown at 15 to fit within the groove 16 of the trolley wheel, when the bifurcated guide is raised by drawing down on the pulling rope.

Normally when the trolley is riding underneath the trolley wire in the usual way, the bifurcated end of the guide drops down as shown in Fig. 1, with the forks below the wire. Should the wheel become accidentally dislodged, or should the operator desire to change the trolley wheel from one wire to another, he draws down upon the pulling rope 4 which at once raises the bifurcated end of the trolley guide and brings the curved portion 15 within the groove in the wheel, so that for the time being, the groove of the wheel is, as it were, extended upwardly and flared outwardly to the extent of the opening between the forks 2, 2. The guide, therefore, gives ample space for the operator to allow the wheel and its guide to be easily brought underneath the wire and embrace the wire between the forks. Then allowing the pole to rise, the trolley wheel is guided directly to the wire. The construction under which the guide bar is arranged to enter the groove of the trolley wheel insures the proper position for the forks, and the wheel will be accurately guided to the wire.

The advantages of my construction will be evident from the foregoing description.

The clamping is accomplished by tightening the single bolt 11 and a shoulder 18 is provided for the plate 9, which acts as a ful orum to bring the requisite pressure to bear upon the trolley pole and to prevent any binding on the bolt 5 which acts, asthe pivot pin for the guide.
